# Print
-## Direct print to Brother
+## Garbled text
-Use pdf 1.3
+LibreOffice Writer 7.5 exports PDF 1.6 files
+with embedded subset fonts,
+which renders garbled text
+e.g. using "direct print" from a USB dongle
+on a Brother HL-4040CN Laser printer.
+A workaround is to [downgrade](#Downgrade) to PDF 1.2 like this:
-Convert pdf:
+ ps2pdf12 infile outfile
- localps2pdf
+## Unsupported PDF data
-...or try tab-complete for alternative scripts,
-or look at underlying scripts `pdftops`and `pstopdf13`.
+Some PDF generators,
+e.g. from Deutche Bahn or Microsoft Word on Windows,
+contains some yet unidentified PDF data,
+which is replaced by an error message
+e.g. using "direct print" from a USB dongle
+on a Brother HL-4040CN Laser printer.
+A workaround is to [refry](#Refry) like this:
-## Direct print odd format
+ pdf2ps infile - | ps2pdf12 - outfile
+
+or using this custom wrapper, where available:
+
+ localpdf2ps2pdf infile
+
+If the above fails to work,
+then try replace `pdf2ps`
+with either `pdftops` or `pdftocairo`.
+Beware that options may differ.
- pdftocairo -pdf -paper A4 infile outfile
- pdftops %f
- ps2pdf13 infile outfile
